Video capsule endoscopy findings in dogs with chronic enteropathy and in healthy dogs

Abstract Background Video capsule endoscopy is a noninvasive technique for evaluation of the gastrointestinal tract. Objective To investigate the safety of using the video capsule ALICAM in dogs with chronic enteropathy (CE) >10 kg, and to compare macroscopic gastrointestinal morphology between CE dogs and healthy controls (HC). Animals Fifteen CE dogs and 15 similarly breed, age and body weight matched HC. Methods All dogs underwent a clinical work up including blood analyses, fecal samples, abdominal ultrasonographic examination, and blood pressure measurement. The dogs were withheld from food for 16 hours before and 8 hours after they PO received an ALICAM. All recordings were quality assessed, and blindly evaluated by 2 trained observers. Results The median age of CE dogs and HC was 3.3 (interquartile range [IQR] 2.5‐5.9) years and 4.7 (IQR 3.3‐5.6) years, respectively. The median body weight in the CE dogs and HC was 25.9 (IQR 20.6‐30.9) kg, and 29 (IQR 16.2‐30.5) kg, respectively. Complete recordings of the gastrointestinal tract were obtained from all dogs without complications. No significant differences were found between groups regarding number of abnormalities such as irregular mucosa, erythema, nonbleeding erosions, bleeding erosions, and dilated lacteals, as well as severity and extent of the abnormalities. Conclusions and Clinical Importance The use of ALICAM for evaluation of the gastrointestinal tract in CE dogs and HC seems safe and feasible regarding gastrointestinal transit and macroscopic morphology assessment in dogs >10 kg. Abnormalities were found in similar proportions in CE dogs and HC.
